Interface SourceValueRepresentation<T>

public interface SourceValueRepresentation<T>

Implementations of this class transform canonical representations of the resource data to and from source representations.

Nested Class Summary

Nested Classes

Modifier and Type	Interface and Description
static interface	SourceValueRepresentation.SourcedRef this class represents the identity of a resource, providing access to its internal identity and source identity.
static interface	SourceValueRepresentation.UriResolver Resolver to translate source locations into references.
static interface	SourceValueRepresentation.UriRewriter Rewriter to translate references into source locations.

Field Summary

Fields

Modifier and Type	Field and Description
static SourceValueRepresentation	DEFAULT Default implementation for source value representation that are the same as the canonical value representation.

Method Summary

Modifier and Type	Method and Description
byte[]	fromCanonical(SourceValueRepresentation.SourcedRef ref, T data, SourceValueRepresentation.UriRewriter rewriter) Converts the given canonical representation of the value to a source representation
boolean	hasLocationDependencies(T data) returns whether the given canonical data has source location dependencies
boolean	isLocationDependent() returns whether this representation is location dependent
T	toCanonical(SourceValueRepresentation.SourcedRef ref, byte[] data, SourceValueRepresentation.UriResolver resolver) Converts the given value from source representation to canonical representation.

Field Detail

DEFAULT

static final SourceValueRepresentation DEFAULT

Default implementation for source value representation that are the same as the canonical value representation. This implementation assumes that the resource does not represent its dependencies as source locations.

Method Detail

toCanonical

T toCanonical(SourceValueRepresentation.SourcedRef ref,
              byte[] data,
              SourceValueRepresentation.UriResolver resolver)
       throws java.lang.Exception

Converts the given value from source representation to canonical representation.

Parameters:

ref - a reference to the value

data - value to be converted to canonical representation

resolver - a URI resolver to translate source locations into references

Throws:

java.lang.Exception

fromCanonical

byte[] fromCanonical(SourceValueRepresentation.SourcedRef ref,
                     T data,
                     SourceValueRepresentation.UriRewriter rewriter)
              throws java.lang.Exception

Converts the given canonical representation of the value to a source representation

Parameters:

ref - a reference to the value

data - the canonical representation to be converted

rewriter - a URI rewriter to translate references into source locations

Throws:

java.lang.Exception

isLocationDependent

boolean isLocationDependent()

returns whether this representation is location dependent

hasLocationDependencies

boolean hasLocationDependencies(T data)

returns whether the given canonical data has source location dependencies
